    description
    The present invention relates to a mounting device for mounting a mechanical clock, with a drive unit, a control, regulating and measuring unit and a gripping device with two gripping arms, which can be brought into contact with a winding crown of the clock, and with a jig for the clock.
    State of the art
    Wrist or pocket watches that are mechanically designed to achieve the necessary energy to operate usually from a spring that must be stretched or raised at regular intervals. If this is not done, the clock will stop and it must be reset if necessary. This is particularly associated with great effort when the clock is still connected to other elements, such as a calendar, moon phases or the like.
    An outside of the watch case sitting at the end of the pendant, mounted on the (elevator) shaft thumbscrew, by turning a tension spring is tensioned.
    With a switching mechanism (pusher in the edge of the case, pulling out the crown) can be adjusted with the crown and the hands. The term "crown" resulted from the occasional shape of this thumbscrew. In the following, the term "elevator crown" will be used.
    If a regular mounting can be prevented, either a so-called automatic clock or an electrically operated clock can be used. For the automatic watches so-called watch winders are provided which regularly move the clock winder arranged in the watch, if it is not worn on the arm.
    There are already known from the prior art Aufziehvorrichtungen for mechanical watches, which have a watch carrier with which the clock is positioned in a desired orientation or orientation in the mounting device and having a gripping device, with a winding crown of the positioned clock can be taken to then allow by rotating movements, a winding of the clock.
    For example, from US 5 988 871 a mounting device for mechanical watches are known, which are held by a jig. To mount such watches whose respective winding crown is gripped by a gripping device having a plurality of claws. This gripping device can then be offset by an electric drive in such a rotational movement that it performs an oscillating movement. Here, a slip clutch ensures that over-rotation of the Aufziehmechanismus can not take place. Here, the design of the gripping device corresponds to a pair of pliers with two gripping arms.
    Disadvantages of the prior art
    As a rule, mechanical watches have different elevator crowns. They differ in particular with regard to their diameter. As result in the known from the prior art collet different points of attack on the winding crown, this can easily be mechanically stressed and thus damaged.
    If such a gripping device used in particular in such watches that are pending for sale, for example, immediately after production before their shipment or even in the presentation in shops, the seller is forced to replace the possibly damaged crowns.
    Furthermore, it is known that immediately after the production of such watches prior to their transport first provisional crowns touches that may well suffer damage, thus ensuring that the clocks are actually fully wound. Only immediately for the transport of such watches, the respective provisional crown is replaced by a new perfect winding crown, which in turn makes the clock more expensive. Also, a mounting a mechanical watch immediately before a sale with the known gripping devices in which a collet engages around the respective winding crown, this can be damaged because the edge-like formation of the free ends of the collet can compress the commonly present corrugations of the winding crown. After completing the winding, the seller is forced to put on a new crown.
    Many embodiments of watches have so-called shock horns. These are arranged on both sides of the respective winding crown elements that prevent that under mechanical stress of the clock in the crown area, the axis on which the winding crown is located, bends. Because of such shock horns but it is almost impossible with such collets to embrace the respective winding crown and at the same time to perform the necessary Aufziehdrehbewegungen, as these collets on the shock horns.
    Object of the invention
    The object of the invention is to provide a mounting device for mechanical watches and a suitable gripping device for this, with which the risk of possible damage to the elevator crowns of these watches is minimized by the winding process or even completely eliminated.
    Solution of the task
    The object is solved by claim 1 and claim 6.
    Advantages of the invention
    The basic idea of the invention is to simulate the mounting of a mechanical watch to be wound up with the fingers of a human. To raise a clock, you grip with two fingers, especially with your fingertips, the winding crown of a clock and moves the winding crown between your fingers back and forth. The back and forth movement of the watch is achieved.
    In accordance with the present invention is achieved mainly by the proposed wheel elements (replica of the fingertips) for mounting the mechanical watches, that their elevator crowns are only linearly on two opposite sides with these when mounting in contact, with a rubber-like design of the Wheel elements of this contact can also be done without damage.
    It can be advantageously provided that for a determination of a provided with a bracelet and aufziehenden clock a clamping device is provided, with which the bracelet of the clock are fixed by at least two spreading and dislocation of the respective winding crown can not occur when mounting, whereas otherwise possible damage to the winding crown is possible. In this case, three spreading elements are possible, whereby an improved static fixation of a respective bracelet and thus the clock itself is given. Alternatively, tensioning devices can be provided which receive such watches, which have no bracelet. The aim here is to design and position the tensioning device such that the winding crown can be encompassed by the wheel elements.
    In particular, it is advantageous if the clamping device is formed in relation to the wheel elements in several degrees of freedom to these deliverable and / or pivotable. This offers the possibility that the wheel elements for their use do not have to move axially on the respective elevator crowns, but can remain fixed in its axial position, whereas then the clamping device with the fixed clock is axially moved to the wheel elements, namely so that the respective winding crown with the wheel elements come to a meshing contact.
    For this purpose, an axial displacement of the clamping device, it is expedient if this is connected via a hammerhead-like connecting arm with the housing, which serves to accommodate the drive unit, so after the manner of a slider, that with the help of this connecting arm of the axial distance Clamping device to the wheel elements via an actuator is adjustable.
    Finally, it may be advantageous if the clamping device is also designed to be pivotable, so that so-called 2/4-clock positions are possible in which more elevator crowns can be operated by the wheel elements.
    In the gripping device advantageously the fingers of a human hand are imitated. This bionic approach is that a gripping device consisting of two finger-like gripping elements, the respective winding crown engages at certain points, namely opposite from above and from below.
    The gripping device may thus have at least two or more gripping arms, which may be formed zero, one or more articulated, wherein at the free ends of the wheel elements are mounted, which are driven for example via flexible shafts of the drive unit. The wheel elements may preferably be mounted with a rotation axis on the gripping arms and consist of a material which is similar to the hardness of a finger. This means that the material is inherently soft, but nevertheless should be sufficiently hard, so that a good stiction arises between the wheel elements and the circumference of the winding crown. Preferably, the wheel elements are rubbery wheels. Basically, it is not necessary that wheel elements are present, since no permanent rotational movement must be performed. An oscillating reciprocating motion can also be performed by differently configured contact elements, which represent, for example, only a semicircle.
    In order to prevent that the shaft of the winding crown is bent due to the gripping force of the gripping arms, the wheel elements are preferably to be arranged such that they are arranged opposite each other during the Aufziehvorganges. As a result, although the corresponding forces act on the winding crown, they cancel out again, relative to the shaft of the winding crown. Thus, no bending moment acts on the shaft of the winding crown. To avoid overdetermination of the drive, it can also be provided that only one wheel element is driven, the other wheel element then being designed as a freewheel.
    Another advantage of the gripping device according to the invention is that, in particular, such watches can be mounted, which have so-called shock horns in the region of the winding crown. This is due to the fact that the wheel elements are arranged opposite each other and so only have a linear contact with the respective winding crown. As a result, a large area of the elevator crown is free and can be occupied by, for example, shock horns. Like a human hand, the gripping device engages around the respective winding crown arranged between the shock horns, with the gripping arms lying opposite one another, and then displaces the crown into a corresponding rotary movement.
    This rotational movement can be performed in different ways. On the one hand it can be provided that an oscillating reciprocating motion takes place, so that at least when pulling in one direction, the corresponding winding process of the clock is triggered. An alternative is that the wheel elements move away from the winding crown for a short time and then put on again accordingly and move the crown in the same direction. Due to the fact that no complete encompassing or re-clamping, comparable to a collet, is necessary, the wheel elements during the entire Aufziehvorganges can always remain in contact with the winding crown. By appropriate control, the wheel elements in any direction (forward or backward) can be moved.
    In addition, it can be provided that a positioning element is provided on the gripping device. This also touches the winding crown, but at the front side. Due to this contact on the front side, the gripping arms can be positioned accurately so that the wheel elements contact the winding crown directly over the preferably entire width of the crown. At the end-side contact point, for example, a spherical bearing, which is spring-loaded, may be provided.
    In order to prevent overwinding of the clock to be wound up, it is expedient to provide a measurement or regulation which measures the occurring tensioning force on the wheel elements. As the time increases, the pull-up force increases and is simultaneously measured in relation to the increased current on the motor that drives the wheel elements. If the current exceeds a defined value, the drive switches off. The winding process is over.
    The drive of the wheel elements can also take place via a corresponding transmission. If the electric motors are chosen to be sufficiently small, the drive can also be arranged directly directly on the wheel elements. However, due to the structural design of the corresponding clocks, it is advantageous if the drive units (motor) are arranged outside the wheel elements. In addition, the free ends of the "fingers" of the gripping device are not burdened by an additional weight more. As a result, a simple positioning of the wheel elements on the winding crown is possible.
    Further, it is in a Aufziehvorrichtung for mounting a mechanical clock, which is equipped with a drive unit, a control, and measuring unit and a tensioning device for the clock and a gripping device with two gripping arms, the latter in contact with a winding crown the clock can be brought, particularly advantageous if the gripping arms have wheel elements which are coupled via a zero, single or multi-joint drive shaft with the drive unit. Here, the contact can be made with the arranged at the end of the gripping arms wheel elements such that the mutual distance of the gripping arms to each other and / or whose distance relative to the clamping device is adjustable, or that the gripping arms and / or the drive shafts formed telescopically in their respective length changeable become.
    Further advantageous embodiments will become apparent from the following description, the drawings and the claims.

    Description of the embodiments
    In Fig. 1 as a first embodiment schematically an inventive Aufziehvorrichtung A is shown, which has a gripping device 1 for a winding crown 2 of a mechanical clock 3. The mounting device A further has a drive unit 4 and a control, regulation and measuring unit 5.
    The gripping device 1 is designed such that it has at least two trained as a multi-joint drive shafts gripping arms 6a, 6b, which may also be formed zero articulated or lumped or multi-jointed. Nullgelig means that these are rod-like, and are mounted either rigid or displaceable.
    On the side facing away from the drive unit 4 and thus at the free ends of the gripping arms 6a, 6b drive elements in the formation of wheel elements 7a, 7b are mounted such that they are rotatable and drivable in the direction of arrow 8a or 8b and in its opposite direction , The wheel elements 7a, 7b touch the circumference - denoted by 2u - the winding crown 2 in order to pull the winding crown 2, which is mounted on a shaft 9 of the clock 3 by frictional engagement.
    The drive unit 4 for driving the wheel elements 7a, 7b (and possibly also the gripping arms, depending on the embodiment and storage) is not shown in detail in the drawing, since it has a conventional structure, that of the prior art is known. For this purpose, means are provided which execute the gripping movements accordingly. The same applies to the drive shafts for the wheel elements 7a, 7b of the gripping device 1. Preferably, these are driven by a multi-joint drive shaft, so that as little weight as possible at the ends of the gripping arms 6a, 6b is present. In order to prevent over-determination, it may be provided to drive only one wheel element, for example the wheel element 7a, whereas the further wheel element 7b has a freewheel.
    For automatic control of the drive, the control-regulating and measuring unit 5 is provided which measures, inter alia, the current intensity for the drive unit 4, because with the increasing duration of the Aufziehzeit the winding force increases, as provided for each in the clock 3 Spring is always stretched. This has the consequence that the current strength within the drive unit 4 increases. This rising current in turn is detected by the control, regulating and measuring unit 5 detected analyzed, and with a corresponding exceeding of a certain amount of current exceeds the drive unit 4 due to the controlled variable, which is predetermined by the control, regulation and measuring unit 5 from , The winding process is over.
    2, a left side view of the first embodiment is shown schematically again, in particular for explaining the function of the drive of the wheel elements 7a, 7b, and that these are arranged at the free ends of the joint or gripping arms 6a, 6b, that they are pivotable in and against the direction of arrow 10. In the embodiment shown here, the wheel elements 7a, 7b abut on the outer circumference 2u of the crown 2 and set the shaft 9 of the winding crown 2 in rotation.
    In particular, can be seen very clearly from this view that due to the presence of shock horns 11 on the clock 3, a device of a collet for performing a rotational movement little to no space could occupy. Only due to the design of the free ends of the gripping arms 6a, 6b as wheel elements 7a, 7b, which can be set in rotation, an operation of such an embodiment of the clock 3 is possible.
    In the second illustrated embodiment in Fig. 3 a Aufziehvorrichtung B with a gripping device 1a is provided in contrast to Fig. 1 and Fig. 2, that the gripping device 1a has an additional positioning element 12. Here, the positioning element 12 is arranged centrally and is provided for the frontal contact with the winding crown 2. The positioning element 12 can be positioned in and against the direction of the arrow - denoted by 13 - on the one hand independently of the gripping arms 6a, 6b or depending on these. In particular, the positioning element 12 serves to more accurately determine the position of the wheel elements 7a, 7b on the winding crown 2 by the positioning element 12 comes to bear the end face of the winding crown 2. As a result, the conditions on the winding crown can be determined and the points of application of the wheel elements at the circumference of the winding crown can be determined.
    In Fig. 4 is shown as a third embodiment, a perspective section of a mounting device C, which is equipped with a gripping device 1b, which has zero-joint gripping arms 6c and 6d, at their respective free ends, the wheel elements 7a and 7b are provided.
    As a watch carrier for a mechanical watch 3a with a bracelet 3b, a jig 14 is provided which has two spreading elements or spreading jaws 15a and 15b, which can be held or released via a latching device 17 in compressed position via a spring pin 16. In Fig. 5, the spread position of the expansion elements 15a, 15b shown in which the bracelet 3b stretched on the jig 14 and thus the clock 3 is clearly fixed.
    4, the gripping device 1b is integrated in a housing 18 of the mounting device C, that the gripping arms 6c and 6d are formed in the form of continuous drive shafts, which, according to the double arrow - 19 - apart or driven towards each other can be in order to contact the winding crown - referred to as 2a - accordingly. It is also possible that the gripping arms 6c and 6d are formed telescopically, so that they can be moved from and to the elevator crowns, with simultaneous adjustability according to the double arrow 19th
    In the case of further crowns 2b and 2c, which serve, for example, for adjusting various calendars which are present on the watch 3a, FIG. 5 shows a possibility, as do these crowns 2b and 2c with the wheel elements 7a , 7b can be rotated. For this purpose, the jig 14 is designed so that it can be pivoted, in so-called 2/4 o'clock positions, which can be obtained in each case via not shown locking devices. In Fig. 5, the 2 o'clock position is shown, which is obtained in that the jig 14 is pivotally mounted on the free end of a hammerhead-like connecting arm 20 which is slidably in communication with the housing 18.
    This connecting arm 20 is guided with its crosspiece - designated 21 - in the housing 18 such that an actuator 22 acts on this, with which the connecting arm 20 and thus the jig 14 can be moved axially parallel to the gripping arms 6c and 6d, as indicated by a double arrow 19a in Fig. 4. This means that, for example, when the gripping arms 6c, 6d are fixed in the axial direction, they merely have to move apart, so that it is possible by an adjustment of the actuator 22, for example, to move the winding crown 2a of the clock 3a between the open wheel elements 7c and 7d , in which case they then move back together and touch the winding crown 2a linearly, and then take the winding crown 2a during mounting by means of a static friction. A release then takes place in the reverse manner.
    Finally, in Fig. 6 is a simplified end view of a jig 14a shown as a carrier of a mechanical clock 3a, the three spreading elements 15c to 15e has, which allows a statically balanced fixing of the clock 3a by means of her bracelet 3b. In Fig. 6, the clamping element 15e is shown already applied to the bracelet 3b, whereas the clamping elements 15c and 15d are still held by a latching device 17a in its initial position and released according to the latching device 17 in Fig. 5 for abutment against the bracelet 3b can.
    Thus, quite generally a Aufziehvorrichtung with a gripping device and a tensioning device for a aufziehende clock proposed with the different embodiments of elevator crowns of mechanical watches can be gently taken without a constant change of the respective winding crown is necessary before delivery of the clocks. The bionic approach of the gripping devices results in ergonomic and efficient operation of the applicator.
    Overall, the present invention is characterized by a simple handling, which expresses that different 2/4-clock positions are possible. The distances between the wheel members can be easily adjusted, so that a variety of watch case sizes and shapes can be tightened. Another advantage is that watches can be mounted with a crown protection. Finally, the distance from the wheel elements can be adjusted so that no frictional contact with the watch case can take place.
